Probably finished in a rock tumbler with steel media. I've watched a few finishing videos and it seems that if you finish this stuff with iron or steel media it ends up depositing some of that color on the final piece. I've seen others use brass screws or media and those come out much more copper looking.

No offense to the Indian Nations of the continental (and otherwise) US, but this means fuck all in the long run. Tariffs, taxes, treaties, loans, grants, etc are all still done in dollars and as far as the US is concerned anything being paid needs to be converted to USD first. And the Indian nations have exactly zero power to try and do anything about that.

If their money is really that valued, would they spend $50 extra dollars on swag?

People are allowed to spend their money how they want. You and her are making it sound like everyone who spent money on her kickstarter (or at least everyone who spent over an arbitrary amount) is some Hampton's level trust-funder who's just saying they deserve stuff because they have money.

People sent her money for a product. Asking for it, or even demanding it, is not to the same degree as whining for privileged treatment because you're "wealthy".

Her entire rant is about how people feel like they deserve things because they have enough money. She's angry at the power money has over people, so she's directly challenging the authority of the richest backers. It's a declaration of war against those who think their money allows them to be dicks.

That argument has merit, but not in the context of people who paid you for a product. That's why people are thinking this is either an ego trip of a total mental breakdown (leaning towards "fuck it, I'm taking the money, screw yall" myself). She fulfilled, by her own words, 75% of the orders and then just decided that she wasn't going to do anymore. And as far as the "punish the richest" thing: How does she know how rich the different backers are? Someone who was a huge fan could have scrapped up enough for a high reward tier because they wanted to supporter her, while some rich guy could have just bought the cheapest on a whim.

And the idea that she wants someone, or some people, to bankroll her in totality (not even to complete a project, but just to exist) screams of someone with a huge ego. She's basically saying, in my interpretation: MONEY IS EVIL, NOW GIVE ME ALL OF YOURS!
